Cold air in the winter can cause the droop. Are you in a basement or on a slab? Do do have anything on the floor under the plants or tent? Also, if your water is cold that can affect them too.
The floor underneath the reflectix is carpeted, but not super insulated. The closet is in the nose of a fifth wheel, so the floor itself is only about 6" thick. Basically, the plants are in the part of the trailer that hangs over the bed of the truck when towing, if that helps the visual.
I have a temperature probe for my multimeter that I will poke down in the soil this morning, after I've had some coffee, and can think again.
it may take a few to several days to see improvements, that problem didnt happen over-nite... it started days ago but just more noticeable now.. It could be from the cool air, but also looks like little clawing going on the one on right side.. the left side about to start transition from looks of that.. the right side don't quite look at transition yet...the left side doesn't look so bad at all.. was the fan blowing at that right side? am only asking coz that can throw me off about that clawing I may or may not be seeing on that, it could be wind burn... or was where cold air coming in right next to that plant or blowing at it? hard tell on this side of pics if clawing or just wind burn..
Good points,
The fan was in the lower left corner, leaning against the wall, right at the air intakes. It was indeed blowing directly at the CJ (plant on the right). Now the fan is blowing down, from warmer air near the lights. It is a weak little thing, barely more than a glorified pc fan, but combined with the low humidity (20-40%), maybe that was a factor.
I'm kicking myself for not checking the water temp, before I poured it on the plants. Best guess is the water may have been in the high 50's. You can bet I will make sure it's closer to 70f next time!
I wonder if that's why it looked like overwatering? Cold water, cold root zone= not much oxygen to the roots, same as too much water, even though it wasn't? The evaporative cooling of a fan blowing cold air on a damp fabric pot would have only made the situation worse...
Thanks for the help guys, I'll take some more steps to get the root temps up a bit today, and see if that helps.
Meanwhile, I'll pace the floor until they look better!
I love it when non growers say "It's just a weed, it's not hard to grow"
Haha, walk a mile in our shoes, jackazz.
